Gone are the days of 3G and 4G, here comes 5G technology. 5G or the fifth generation technology is based devices operate in different bands from 3 to 300 GHz.
Everyone is enthusiastic over the advent of 5G technology possibly because the speed of the internet will be faster than the 4G and as we all live in virtual realities, we can hardly survive without internet these days.
What is so unique in 5G?
5G is an upcoming network system possessing much higher speeds and capacity and lower latency in comparison to the existing cellular networks. The 5G networks will use a type of encoding known as OFDM.
Orthogonal Frequency-Division Multiplexing (OFDM) is a method of digital signal modulation in which a single data stream is split across several separate narrowband channels at different frequencies to reduce interference and crosstalk.
OFDM is similar to the encoding technique used by LTE (Long-Term Evolution, a standard for high-speed wireless communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies). It increases the capacity and speed using a different radio interface together with core network).
The air interface of 5G will be designed to provide lower latency and increased flexibility than the LTE networks. 5G networks can make use of frequencies that are as low as old TV channels or even as high as the millimetre waves. 5G networks are likely to be networks of small cells such as the size of home routers than huge towers radiating great distances.
5G networks have to be smarter than the earlier network systems and it is claimed that 5G can boost the capacity by around four times more than the current systems with the help of advanced antenna technologies and wider bandwidths.
5G is likely to outshine the restriction and offer at least five times higher speed than 4G. The transfer from 4G to 5G will allow technology to exceed three technical thresholds as per the tech gurus. First wireless internet speeds will transcend cable broadband and also fiber optic cable.
Secondly, the ‘internet of things (IoT)’ will have mass industrial applications for the first time and thirdly, communication lag will fall to one millisecond – faster than the speed at which humans perceive touch response instantaneously. This will surely give rise to new ‘tactile internet’ applications and pave way for remote surgery. Thus, 5G Technology is going to break the barriers and this transition will have a larger and broader economic impact than shifts between previous generations.
Indisputably, consumers will gain the most from this transition, then by network equipment suppliers, cellular tower companies and connected device makers. Once the market for 5G opens ups completely, telecommunication and media companies will gain from this as well.
However, media has to face challenges as well as content distribution changes, cable TV companies will see their value proposition further erode.
If we all remember previous technologies such as 3G and 4G created a boom in the market, 5G is expected to increase the speed and volume of data transfer through the airwaves. Undoubtedly, 5G will be more momentous than previous transitions due to unprecedented speed.
Est Certainly 5G is good news for all of us but this newest will cost more to implement and while the newest mobile phones will probably have it integrated, other handsets could be deemed out of date. A reliable, wireless internet connection can depend on the number of devices connected to one channel.
With the addition of 5G to the wireless spectrum, this could put us at risk of overcrowding the frequency range. The problems with 4G and even 3G aren’t exactly filling us with the hope of an immediate super-fast connection. There are areas where people can’t access 4G and in that case, the rollout for 5G is likely to be very patchy.
5G might enthuse all of us but it will come with a huge price tag. Dr. Cindy Russell in ‘A 5G Wireless Future’ wrote that ‘3G, 4G, 5G or a combination of zapping frequencies might give us immense connection and entertainment but at a potentially steep price’.
Dr Russell states that 5G will lead us to some diseases like arrhythmias, heart rate variability, bacterial effects, antibiotic resistance, immune system effects, chromatin affects altered gene expression and cataracts.
Dr Yuri Feldman, Department of Applied Physics, Hebrew University of Jerusalem, said that 5Gs millimeter and sub millimeter waves will uniquely interact with human skin and lead to preferential layer absorption.
Moreover, in 2011, the World Health Organization’s International Agency for Research on Cancer classified RFR as a potential 2B carcinogen and specified that the use of mobile phones could lead to specific forms of brain tumors.
A US National Toxicology Program study noted that male rats exposed to RFR for nine hours a day over two years developed rare forms of tumors in the brain and heart, and rats of both sexes developed DNA damage.
So are we ready to jeopardize our health over technology for which we are going berserk? Ponder over what we want – 5G technology or healthy peaceful life surrounded by our kith and kin. Do we need or should we embrace 5G with all its pitfalls, we will decide and none else.
